refactor: replace ghostty wrapper with proper CLI actions for terminfo cache management

Browse Source 
- Add +list-ssh-cache and +clear-ssh-cache CLI actions
- Remove ghostty() wrapper functions from all shell integrations
- Improve variable naming in shell scripts for readability

Addresses @00-kat's feedback about CLI discoverability and naming
consistency. The new CLI actions follow established Ghostty patterns
and are discoverable via `ghostty --help`, while maintaining clean
separation of concerns between shell logic and cache management.
